My slings used the most-




Loaded with lighter stone. The stone in the bottom of the pics goes with the deer-hide slings, most of the pieces weight little(around 2 oz) because those are light slings with light stone for accuracy and beginning slingers.
The rockman is almost worn out, look at the release tassel.
The green and black with leather pouch sling is from timu. I haven't used it much.
The stone leaded into the rockman weighs about 7 oz and is potatoe shaped.
The stone loaded into Timu's sling weighs a little less... it is some super heavy rock IMO... ive got no idea what it is.
The balaric is jute loaded with clay bicones.
The ammo at the top is literally dirt.
I just went outside, dug down a foot, dug up about 5 pounds of material, took it on the deck, then rolled it up. No screening, there is still some lumps of mulch etc in it... but they still sling good.
